Protection against mould - protection of the building fabric
Mould initially forms almost invisibly and quite quickly. Whenever warm air comes into contact with cooler surfaces and falls below the dew point in the process, condensation water precipitates on the wall or windows. Due to heat bridges, such cooler surfaces can also be often found in new buildings. It is even worse if air flows out of the house due to leaks in the building shell. In this case the moisture precipitates in the wall structure, causing invisible damage. When it is detected, it may already be too late.
Because remediation is complicated and expensive or, in extreme cases, even impossible as soon as the mould has settled in the wall structure.
Convenience ventilation systems always provide sufficient air circulation and discharge the humid air from the house, preventing mould damage and protecting your building fabric in the process.
